My invention relates to rings and ring travelers of the vertical typefor spinning and twist ing machines.

'More particularly the present invention ap- 5 pertains to rings andtravelers wherein a constituent part of the traveler. head includes adownwardly and rearwardlydlrected nose disposed to prevent accidentaldisengagement of the, thread from the head, and to maintain the 10traveler shank in contact with the inner face of the ring. Such aconstructiony is disclosed in Letters Patent of the United States No.1,880,084 issued to me Sept. 27, 1932, and on which the presentinvention is an improvement.

In this type of traveler the free endI of the nose is, in runningposition, in contact with or closely adjacent to the outer face ofthey-ring, and, in threading position, the nose is so slightlyinterspaced from the latter that the insertion of the delicate thread orfilament into the traveler head through the vrestricted space betweenthe nose end and ring prior to starting the spindle, or in other wordspiecing up the end," has a tendency to split, separate, or abrade thefilament. y

Essential objects of my invention are, while retaining the advantagesinherent in a traveler nose disposed downwardly and inwardly towards theouter face `of the ring, to avoid injury to the lament during thethreading operation; to facilitate the introduction of the filament intoa ring traveler head; to prevent accidental escape of the sametherefrom; and to attain these results in a simple, strong, andinexpensive structure adapted for operation upon internally recessed ornon recessed rings.

To the above ends primarily my invention consists in such. parts and insuch combinations of parts as fall within the scope of the appendedclaim.

In the accompanying drawing,

Like reference characters indicate like4 parts throughout the views.

As herein illustrated I2 represents a spinning or twisting ring of thevertical type, seated in the usual ring rail I3 of a spinning or twisterframe.

My novel traveler of the vertical type I is formed from a wire or rod ofany desired or preferred cross sectional contour. It comprises 8 anelongated shank I8, a foot Il ,upon its lower end, and a head I8connected to the upper end of the shank by a bend I9. 'I'he headincludes a base portion 20 extending rearwardly and upwardly from thebend, thence a forwardly extending top lportion 2|, and lthena noseportion 22 extending downwardly and rearwardly towards the travelershank and toward the outer face of the ri'ng as well as in substantialalignment with the bend I5, and in the vertical plane of the remainderof the traveler. Integral with the free end of the nose portion is anopen loop 24 whose convex intermediate or bearing portion 25 is directedtowards the ring, and its free end portion 28 is directed upwardly andforwardly. 20

The bearing portion 25 is spaced from the upper portion of the shank I6preferably approximately the width of the thickness of the ring whenintended primarily'for lubricant spreading purposes, butwhen the desiredfunction of the traveler is solely the retention of the filament fromaccidental escape from thetraveler head the space between the shank andbearing portion may if desired be greater than that indicated.

The ring I2 is provided with one or more, in this instance two,lubricating recesses or grooves 28. Such grooves are shown in Figures land 2. These grooves may, if desired, be omitted, as shown in. Figure 4,if the lubricant has been initially manually applied to theinner surfaceof the ring, or if the sole desired purpose is the prevention ofaccidental escape of the thread or filament from the traveler head.

The form of traveler head may be changed to accommodate differentdiameters of the bers to be twisted provided that the nose portion beinwardly and downwardly directed and its described terminal loop or itsequivalent be present.

A modified form of my novel traveler is shown in Figure 4 and includesan open loop 30 from whose bearing portion 3i its free end 32 is di.-rected forwardly and upwardly upon the side of the nose opposite to thatof the end portion 26 of the loop 24.- In the modification shown inFigure 5 the bearing member consists of a closed 50 loop 33 wherein theloop'end 35 overlaps the nose.

To perform the threading operation the 'spindle is stopped, whichreleases the tension on the a slack vertical position hanging loosely byits head from the upper edge of the ring. with its foot Il dependingslightly below the lower edge thereof. The traveler is next manuallyelevated lifting the loop 24 out of contact with the -ring aiordln'g, asshown in Figure 2, a space or channel Il for the insertion oi theillament 36. held horizontally, therethrough into the interior'oi thehead as at 3B, and the travelerl allowed to drop into dependingposition. When the spindle is restarted the traveler and filament resumetheir original running positions. In Figure 2 the filament is shownabout to be inserted.

In running position the contact of the loop with the ring preventsaccidental escape of the lament from-the ring, but escape occasionally.

occurs while the spindle is inactive and the ring rail is continuing itstraverse action with thev traveler in slack position. Under theseconditions, the torsional energy stored in the filament creates one ormore tightly twisted stiff loops which sometimes elevate the traveler,and the unlooped portion of the iilament crawls from its position shownin Figure l along the top oi 'across the bottom edge of the ring, and ahead including an inwardly and upwardly and then outwardly directed topportion adapted to engage with the top edge of the ring, an inwardly anddownwardly directed nose portion upon the outward end of the topportion, and a loop 4comprising a convex bearing portion formed bybending Iinwardly and upwardly said nose portion, said loop engageablewith the outer ring face when the traveler is in running position andterminating in a free end portion nextending E0 upwardly and outwardlyand lying between said nose portion and the outer face of the ring. v
